We have analyzed chemical constituents of the free-standing ferroelectric liquid crystal film supported by rigid anisotropic micro-fiber network polymer(20%) formed with photopolymerization-induced phase separation, for a future flexible sheet display which will implement features of ease of large-size fabrication and light-weight panel structure. The liquid crystal and polymer materials segregated from their homogeneous solution were individually dissolved by different solvents, and then examined by liquid chromatography methods. The extracted liquid crystal had a high purity more than 96% and contained decomposition products less than 3% and a little amount of remained monomer less than 0.3%. Otherwise, the evaluated molecular weight of the segregated polymer showed broad width. distribution and a comparatively small polymerization degree of about 100.
